Waimano Valley Hike

[WaianaeCrider]

Took my daughter and 15 year old grand daughter on a short hike the other day.  Waimano Valley along the stream is now a jungle of what I believe of Pinanga coronata.  I use to hunt wild boar in this area in the 70's and these palms WERE NOT present in the valley.  Over the past decades Pinanga coronata has become invasive in many of the leeward Ko`olau valleys.  I wonder if birds or pigs carried the seeds over the mountain from Hoomaluhia gardens?

The photos following the first  are NOT sideways on my computer.  Not sure why this program turned them.  Never happened before.

 

Also saw a few of this.  Could be young Roystonea regia?

 

Didn't cross the stream to check the fan palm.  Could it be Livistona chinensis; ?   There are MANY of these in other valleys closer to Honolulu.

It’s a shame exotic palms have become weeds in such a unique environment islands in the Pacific Ocean have been vulnerable to habitat destruction since early exploration.

It is beautiful to me but when a species is introduced in an otherwise pristine environment it can become a problem. I was on Kuaii and they were dealing with bougainvillea in mass as it was taking over and strangling other plants. Harry

It sucks seeing beautiful plants turn to mosnters without proper competition in a place thats not their own.  I love plants, but that aspect of their evolutionary path and its intersection with humans is a big concern to me.  Hopefully the state gets more active in the control of invasives there.  I would do it as my job too if i lived there and it was possible. Like the helicopters that scan for miconia and radio it in so they can go kill it before it takes over a mountian side.  Lots of money goes into fixing human screw ups.
